Recently a customer of mine added oil to his V-series Mycom screw compressor with a pneumatic barrel pump through a valve on the suction line with the unit running. Once notified I was instantly concerned about the possibilty of premature failure to the sleeve bearing and or other internal components.
It was also brought to my attention that the compressor once online and running for 10 minutes, starts to leak ammonia from the shaft seal. The leak disappears once you shut the machine down. This leak materialized only after the customer added oil in the aforementioned fashion.
Does adding a cold, high viscous oil to an operating screw compressor in an oil slugging manner explain the ammonia leak or are the two possibly unrelated?
